HALLOWEEN: what's an Atheist to do??

Hello fellow TA members. With halloween in just a few weeks, I was wondering if any of you have seen or thought of any good atheist costumes. I'am somewhat at a loss since one cannot really "dress" as an Atheist, and because I don't really want to go as an upside down cross. When it comes to a costume I suppose expressing anti-theism might be easier than Atheism, but any ideas of the sort would help.

P.s. Not sure how evolution as a theme would play out in costume, but Im open to the idea of that too.

We need to find some Richard Dawkins, Chris Hitchens, Sam Harris, Neil deGrasse Tyson, masks ! Or how about an Obama mask? (I still think he's a closeted atheist.) Too bad, the majority of masks in the U.S. will eventually be masks of Jeebus Krist. That's an easy costume.... Dark skinned, full faced beard, long hair, and a robe plus sandals to represent the Medieval Ages not only in looks but in mentality. Oh Holy Night , is what they'll be singing on Hallowe'en instead of The Monster Mash. HAAAAAAAAAAAAAAAAAAAA......

It says Cap. America is protestant… meh, details. Since Marvel is into posing the question “What if?” I think it falls in line with Marvel tradition to ask “What if Cap. America was an atheist?” Problem solved!
